Last April, Mosley was subpoenaed to face charges of sexually assaulting a teen in Minnesota. Mosley's half-sister testified Friday that Mosley had called the girl's mother multiple times after he was subpoenaed.

Prosecutors say he then drove to Brown's Brooklyn Park home to silence the girl, but she wasn't there. Mosley's attorney, Travis Keil, has said Mosley had no motive to kill the victims.

Mosley's trial resumes Monday.
